What is "kritosaurini"

Kritosaurini (roughly equivalent to Gryposaurini) is a clade of saurolophine hadrosaurid dinosaurs from the Late Cretaceous.

A tribe Kritosaurini was first proposed by Michael Brett-Surman in 1989.

The clade was first defined in 2013 by Albert Prieto-Márquez as "The most exclusive clade of hadrosaurids containing Kritosaurus navajovius Brown, 1910, Gryposaurus notabilis Lambe, 1914, and Naashoibitosaurus ostromi Hunt & Lucas, 1993".
